ADJUSTABLE MULTIPLE DISK AND SHREDDING HAMMER.

Application filed. July 30, 1919, Serial No. 314,244. Renewed January 30, 1922. Serial- No. 532,880.

To all whom it may concern:

3e it known that I, EDWARD H. FRICKEY, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in an Adjustable Multiple Disk and Shredding vHammer, of which thelfollowing is a speciin proper alignment with each-other, and

hammers located between the disks and hingedly supported between the same by pins passing through the apertures.

'21 pair of the supporting disk.

A further object of my invention is to construct a mechanism WhIGl'l is used in conjunction with crushers in which material of various kinds is to be crushed into small particles, the improvement consisting of placing a plurality of perforated disks on the shaft and between said disks are pivotally mounted a plurality of hammers and the arrangement of the perforations are such that the hammers ma be adjusted in order to bring the outer e face of the hammer on its peripheral radius as the contacting surface of the hammer becomes worn by constant use.

Another object of my invention is to construct the hammers in such a manner that as the contacting surface becomes worn, this worn surface can be ground down and the hammer removed and reversed and adjusted to the next aperture in the disk which is of a height sufficient to take up the ground ofi surface of-the hammer, thus bringing the hammer in proper radius of contact at the same time utilizing a greater portion of the hammer and dispensing with waste.

Figure l, is a side elevation of my invention showing the general structure of the hammer supporting head and the positionof the hammers located therein.

Fig. 2, is an edge view of the same..

Fig. 3, is a detail side yiew of one of the hammers with a part brokenaway.

Fig. 4,'is an enlarged detail view showing hammers located between the Fig. 5, is a sectional view showing the disk hammer head and the manner .of supporting the hammersthereinr shaft and spaced at intervals.

ge or contacting sur-- In referring to the drawings in general 6 indicates a shaft on which is-mounted a plurality of disks 7 and these disks are spaced apart by spacing rings 8, and after the required amount of disks and spacing rings have been applied on the shaft and arranged to properly register one with the other they are properly connected and bound together by the pins, rivets, or bolts 9, which extend through the entire series.

- Each of the disks 7 are provided with perforations 10, and are arranged in rows radiating on the curvilinear spear from near the center to near the periphery of the disk,

the general position and location of the perforations being shown in Fig. 1, of the draw-' away at intervals in the shaft or semi-circular curvilinear 14 and arranged opposite each other so that as the contacting edge 15 ing etween these various disks .are placed of the hammer becomes worn during its continuous operation, the hammers can be removed from their position between the disks and the worn edge ground off as that shown by the dotted lines 16, then the hammer is reversed when replacing the same between the disks and its opening or eye 17 inserted in the next aperture 18 formed inthe disks which apertures are so arranged as to be sufliciently high to take up the wear and allow the point 19 to extend to the proper peripheral radius 20 which is shown by dotted lines in Fig. 1.

The contacting edge of the hammers are also slightly bent to one side as that indicated by the numeral 21, and these bent points of the hammers are arranged to alternate as that shown in Fig. 4, the bent edge of one hammer being to the right, the other to the left and so on with the entire series of hamat an angle to the length of the hammer and-when the hammer becomes ground down to its shortest length it contacts with the stop pins 24 and 25 and the movement of the hammer is limited as that shown by dotted lines in Fig. 1. A,

The essential feature of this invention is to construct hammers that can be re-ground as the surface becomes worn and then to adjust the same to take up theworn surface by adjusting the hammers between the disks; in this manner I find a great saving of material and a pro er adjustment'of the series of hammers so tiiat their contacting or hammering surface is at all times on a proper peripheral radius. As the hammers are ground down as they become worn this edge is then bent to one side as that shown by dotted lines in Fig. 4.

Having fully described my invention what I claim is:

1. A device of the character described having a pivoted hammer consisting of a fiat bar with recessed edges, saidv recesses being arranged in staggered relation on the opposite edges of said hammer.

2. A device of the character describe having a pivoted hammer consisting of a flat bar with its opposite edges having staggered recesses and its outer end being bent to one side and having an inclined surface between its opposite edges.

3. In a. rotary beater the combination of a pair of rotary disks each having openings.

therein at different distances from its center, and a beater pivoted'to said disks; said beater having flat sides and recessed operative edges with its outer end inclined forming an upper contact edge.

4. A device of the character described,

having a pivoted. hammer consisting of abar, with recessed edges, said recesses being arranged in staggered relation on opposite edges of said hammer.

5. A device of the character described, havin a pivoted hammer consisting of a bar with recessed edges, said recesses being subscribing witnesses.
